Pen with a button and ceramic nib

I would love to suggest that supernote creates their pen with a button and maybe even eraser on top. I like their pen, and i am starting to being used to not having a button and erasen on the pen. But having them would make my workflow just perfect. The button for highlight will be flawless.

I know this has been suggested and asked multiple time's, but since i did not see someone from supernote answer or find something official would love to suggest the button again. It seems to be quite requested feature, and i would buy a supernote push up pen with a button in a heartbeat.
